Description

  The present invention is for a hot water system in which components of the hot water system are unitized, such as a fuel cell unit or a heat pump unit used as a heat source for heating and generating hot water, or a hot water storage tank unit for storing hot water for hot water supply. Regarding the unit.

For example, a fuel cell unit of a cogeneration system can be installed at a predetermined location by housing a fuel cell and its accessory equipment in a substantially rectangular parallelepiped outer case and providing support legs at the lower part of the outer case. It is often configured as such. On the other hand, such a fuel cell unit generally has a considerably large weight, such as a weight exceeding 100 kg. For this reason, it is desirable to be able to suspend using a crane when unloading.
Therefore, conventionally, there is a support leg provided with a through hole for passing a sling such as a nylon sling.

  However, according to the configuration as described above, since it is necessary to insert the sling from the side into the through hole of the support leg, the work is troublesome and the workability is poor. Further, when the fuel cell unit is suspended, the sling may come into contact with the upper part of the fuel cell unit to cause rubbing, and this portion may be damaged. Therefore, it is desirable to appropriately prevent such a situation. Such a demand is not limited to the fuel cell unit, but also applies to other hot water system units having a large weight, such as a heat pump unit.

  The present invention has been conceived under the circumstances as described above. When the unit is suspended and moved using a sling, the suspension operation can be easily and appropriately performed. The problem is to provide a unit for a hot water system that can be used.

  In order to solve the above problems, the present invention takes the following technical means.

  A unit for a hot water system provided by the present invention includes a main body in which components of the hot water system are accommodated in an outer case, and a support leg attached to the lower side of the main body, It is a unit for a system, and the support leg part has an upright part that rises upward from a base part that is placed at an installation location. A concave gap that is open in the horizontal direction is formed below each of the above, and a sling is inserted into the gap and hung on the upper wall of the gap at the upper portion of the gap. A downward projecting portion capable of preventing the sling from coming out of the gap is provided.

According to such a configuration, it is possible to suspend the unit for the hot water system using the sling and the crane by inserting the sling into the gap and hanging it on the upper wall portion of the gap. Such an effect is obtained.
First, since the gap is a concave shape that opens in the horizontal direction, the operation of inserting a sling into the gap is easy. Compared with the prior art in which the sling is inserted into the through hole, the sling is Workability when hanging on the unit for hot water system is remarkably improved.
Second, the downward convex portion provided in the upper portion of the gap prevents the sling from coming off the gap. Therefore, when the hot water system unit is suspended, even if a situation occurs in which the unit is slightly tilted, it is possible to prevent a problem that the unit falls off the sling.

  In the present invention, it is preferable that the convex portion is provided by bending a front edge of a horizontal plate portion continuously provided on an upper portion of the upright portion of the support leg portion, or a lower edge portion of the exterior case. It is provided by extending a part of.

  According to such a configuration, the convex portion is formed by using a part of the support leg or the outer case, and the configuration is reasonable compared to the case where the convex portion is provided by using another member. Thus, there is an advantage that the number of parts can be reduced.

  In the present invention, preferably, a first cover for protection formed in a cap shape is detachably covered on the upper portion of the main body, and a sling is used on the outer surface of the first cover. When the hot water system unit is suspended, a first recess is provided that can prevent the sling from being displaced by allowing a part of the sling to enter.

  According to such a configuration, when the hot water system unit is suspended, the sling is prevented from coming into contact with the upper portion of the main body portion and being rubbed, as well as a part of the sling of the first cover. Since it enters into the recessed part provided in the outer surface and is positioned, a suspended state can be stabilized. In addition, what is necessary is just to remove a 1st cover after completing the installation construction of the unit for hot water systems.

In the present invention, preferably, a protective second cover formed in a cap shape using a sheet body is detachably covered on the upper portion of the main body, and the second cover includes: When suspending this hot water system unit using a sling, there is provided a score line for forming a second recess capable of preventing a displacement of the sling by allowing a part of the sling to enter, The second recess can be formed by deforming a part of the second cover along the cut line.
The second cover may be covered on the first cover, or the second cover may be directly covered on the upper portion of the main body without using the first cover.

  According to such a configuration, as in the case where the first cover is used, the effect that the sling can be prevented from coming into contact with the upper portion of the main body portion and being rubbed, and a part of the sling is caused to enter the second recess. Thus, the effect of stabilizing the sling can be obtained. In addition, the second recess can be easily formed in the field using a score line provided in the second cover. Since it is not necessary to form the second recess when the second cover is manufactured, there is an advantage that the manufacturing process of the second cover can be simplified and the manufacturing cost can be reduced.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  The hot water system unit U shown in FIG. 1 is specifically a fuel cell unit such as SOFC. This hot water system unit U has a main body 1 and a support leg 2. The upper part of the main body 1 is covered with protective first and second covers 3A and 3B which will be described later.

  As shown well in FIG. 3B, the main body 1 has a configuration in which the fuel cell and various devices 10 attached thereto are housed in a substantially rectangular parallelepiped outer case 11. A heat exchanger for generating hot water for hot water supply by recovering heat from high-temperature exhaust gas generated from the fuel cell is also incorporated in the main body 1.

  The support leg portion 2 is a portion for supporting the main body portion 1, is configured by pressing a metal plate, and is fixedly attached to the lower surface portion of the bottom wall portion 12 of the main body portion 1. The support leg 2 is disposed below each of both side parts 1a, 1b (front side part 1a, rear side part 1b) in the front-rear direction x of the main body part 1, and is provided as a pair. It has a form extending in the width direction y. More specifically, the support leg portion 2 has a base portion 20 that is placed at a location where the hot water system unit U is installed. Both end portions in the longitudinal direction of the base portion 20 protrude from the lower region of the main body portion 1, and a notched or non-notched hole portion 20a for inserting an anchor bolt or the like is formed in the protruding portion. ing.

  The support leg 2 has an upright portion 21 standing upward from one side edge of the base portion 20, a horizontal plate portion 22 connected to the upper portion of the upright portion 21, and a tip edge of the horizontal plate portion 22 being bent. It has the downward convex part 23 formed by. Between the convex part 23 and the horizontal board part 22, and the base part 20, the clearance gap 4A opened toward the front or back is formed. Both ends of the gap 4A in the width direction y are also open. The gap 4A is located below the front side 1a and the rear side 1b of the main body 1 and can be used to hook the sling 5 as will be described later with reference to FIG. is there. The horizontal flat plate portion 22 corresponds to an example of the “upper wall portion of the gap” in the present invention. As shown by the phantom line in FIG. 3, the upright portion 21, the horizontal plate portion 22, and the convex portion 23 of the support leg portion 2 are shorter in the longitudinal direction than the base portion 20, and from the lower region of the main body portion 1. It is set not to protrude.

As clearly shown in FIG. 2, a gap 4 </ b> B is formed below both side portions 1 c and 1 d in the width direction y of the main body 1. The gap 4B opens outward in the lateral width direction y, and also opens at both ends in the front-rear direction x. The gap 4B can be used to hook the sling 5 as will be described later with reference to FIG. A convex portion 11a that protrudes downward from the upper wall portion 40 of the gap 4b is provided on the upper portion of the gap 4B. This convex part 11
a is configured by extending a part of the lower edge of the outer case 11 downward. The upper wall portion 40 of the gap 4B is, for example, a part of the bottom wall portion 12 shown in FIG.

  The first and second covers 3 </ b> A and 3 </ b> B are placed on the upper portion of the main body 1 when packing the hot water system unit U to protect the main body 1. It will be removed after finishing the work. The first cover 3A is made of, for example, styrene foam and has a rectangular cap shape with an open bottom. However, as clearly shown in FIG. 3A, a first recess 31 is provided in each of the four side surfaces of the first cover 3A. The first recess 31 is useful for preventing the positional deviation of the sling 5 described later.

  The second cover 3B is covered with the first cover 3A, and is configured using a sheet body such as cardboard. When the first cover 3A is made of polystyrene foam, the first cover 3A is liable to be damaged such as chipping by contact with a relatively sharp other object, but the second cover 3B is the first cover. Helps eliminate such disadvantages of 3A. Similarly to the first cover 3A, the second cover 3B has a rectangular cap shape with an open bottom. However, a plurality of pairs of cut lines 33 are provided in the second cover 3B. These cut lines 33 are provided in a form extending from the total of four side surface portions of the second cover 3B to the peripheral edge portion of the upper plate portion 34. In the second cover 3B, when a portion sandwiched between the two cut lines 33 that are paired with each other is pressed with a finger or the like, the portion is depressed, and as shown in FIG. 32 can be formed. The first recess 31 is located inside the second recess 32.

  Next, the operation of the above-described hot water system unit U will be described.

  First, when the hot water system unit U is moved using a crane, the hot water system unit U can be suspended in a manner as shown in FIG. 4 or FIG. 4 and FIG. 5 may be selected as appropriate depending on the conditions of the installation location of the hot water system unit U. However, if such a selection can be made, it is preferable because of its flexibility.

  In the embodiment shown in FIG. 4, slings 5 such as nylon slings are respectively inserted into the pair of gaps 4A and hung on the horizontal plate part 22 as the upper wall part of each gap 4A. When inserting the sling 5 into the gap 4A, it is only necessary to insert the sling 5 from the side of the gap 4A, and the workability is good.

  When the sling 5 is hooked on the crane hook 59 and then the hot water system unit U is suspended, the convex portion 23 functions as a stopper that prevents the sling 5 from coming off from the gap 4A. Therefore, even if the warm water system unit U is tilted slightly when the warm water system unit U is raised, there is no problem that the sling 5 is easily detached from the warm water system unit U due to this.

  For the second cover 3 </ b> B, a second recess 32 is formed at a location corresponding to the sling 5, and thus a part of the sling 5 is allowed to enter the second recess 32. Accordingly, the sling 5 can be positioned, and the sense of stability when the hot water system unit U is suspended can be enhanced. It is also possible to prevent the sling 5 from coming into direct contact with the outer surface around the upper portion of the main body 1 and prevent the main body 1 from being scratched. Since the 2nd recessed part 32 can be easily formed by pressing the location pinched by a pair of cut line 33, this does not become a big work burden.

  In the embodiment shown in FIG. 5, the sling 5 is inserted into the pair of gaps 4 </ b> B and hung on the upper wall portion 40. In this case, the convex portion 11a functions as a stopper for preventing the sling 5 from coming off. Therefore, similarly to the case of FIG. 4, it is possible to appropriately prevent the sling 5 from being detached from the hot water system unit U when the hot water system unit U is raised. Moreover, the sling 5 can also be easily inserted in the clearance gap 4B from the side. Further, with respect to the second cover 3B, the second recess 32 is formed in advance at a location corresponding to the sling 5, so that the sling 5 is disposed in the second recess 32 and the positioning thereof is appropriately performed. The effect that it can plan is also acquired.

  FIG. 6 shows another embodiment of the present invention. In the figure, the same or similar elements as those in the above embodiment are given the same reference numerals as in the above embodiment.

  In the second cover 3 </ b> B shown in FIG. 6A, the cut line 33 for forming the second recess 32 is perforated. Even in such a configuration, it is possible to appropriately form the second recess 32 as shown in FIG. 5B by breaking the perforated portion. As understood from the present embodiment, the score line in the present invention is not limited to a continuous score line, and may be a discontinuous score line such as a perforation.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the hot water system unit according to the present invention can be varied in design in various ways within the intended scope of the present invention.

  In the embodiment described above, a pair of gaps 4A spaced apart in the front-rear direction x and a pair of gaps 4B spaced apart in the lateral width direction y are provided, but only one of these gaps 4A, 4B is provided. It can also be set as the provided structure.

  If the downward convex part for preventing the sling from coming off is configured by using a part of the support leg part or the outer case, an advantage that the increase in the number of parts can be suppressed can be obtained. It is not limited to this. For example, a bolt may be attached to the horizontal plate portion 22 of the support leg portion 2 or the bottom wall portion 12 of the main body portion 1, and this bolt may be a downward convex portion intended by the present invention. Of course, members other than bolts can also be used. In short, the support leg 2 may be any structure as long as the support leg 2 has an upright portion that stands upward from the base portion so that a concave gap that opens in a horizontal direction is formed at a predetermined position below the main body portion. For example, it can also be set as the structure which does not comprise the horizontal board part 22 of the above-mentioned embodiment. The support leg portion 2 may not have a form extending in series in the width direction y of the main body portion 1, and the specific form and number thereof are not limited.

  The first and second covers referred to in the present invention are not necessarily used in combination with each other. A configuration using only the first cover or a configuration using only the second cover may be employed.

  The unit for a hot water system according to the present invention means a unit including devices constituting the hot water system. In a power generation unit using a fuel cell or a gas engine, high-temperature exhaust gas is used for generating hot water. Therefore, these units are included in the concept of the unit for a hot water system in the present invention. Other than the above, a heat pump unit used for hot water heating, a hot water storage tank unit including a hot water storage tank for storing hot water heated by a heat pump, and the like are also included in the concept of the hot water system unit referred to in the present invention. .
